Found in wide range of habitats: swamp whose water is clear, tannin stained, acidic, soft and deficient in dissolved substances; small creek whose water is clear, colorless, with a neutral pH, moderate hardness and deficient in dissolved substances. Feeds on terrestrial and aquatic insects and preyed upon mostly by fish-eating birds and dragonfly nymphs (Ref. 57724).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5079 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
